1. Given the initial and final volumes of the experiment, determine the initial mass of the water and the mass of the ice cube. Show your work. Record your answer in the table above. initial temp of water before ice 28 deg C final temp after ice cube melts 2 deg C initial volume 70mL final volume after ice melts 95mL mass of water = 70mL = 70mg = 0.07g using energy conservation Q = mw(cw)(delta T) How do i set up equation to solve initial mass of water and ice? Is inital mass of water (0.07g) the initial mass of water and is this used in the equation to solve initial mass of ice cube? mw(cw)delta T = mi(ci)(delta T)?

An ice sample at initial temperature Ti (in °C) below zero is introduced into an aluminum calorimeter of mass ma filled with mass mw of water at room temperature of Tr. After thermal equilibrium is reached, the calorimeter contains only water at final temperature Tf. Denoting the specific heat constants for ice, water, and aluminum by ci, cw, and ca respectively, find an algebraic expression for the mass of the ice sample in terms of the given variables and L,...

We did the lab of latent heat of fusion of ice, and I am
confused that what the 'water equivalent' represents.
I thought it is the amount (kg) of water, but it is
mccc according to this lab manual, which unit
is (J/oC).
Please answer what the water equivalent represents and the unit

PROCEDURE Use the 100 mL graduated cylinder to measure and pour 70 mL of room-temperature tap water into a dry StyrofoamTM cup. Record the exact volume in Table 2 on the Experiment 1 Data Sheet. Place the filled cup inside the second cup to increase the insulation temperature. Place and hold the thermometer in the center of the water. Use a timer to time 30 seconds, then measure the initial temperature of the water (Figure 4). Record the value in...

An ice cube of mass 9.0g is added to a cup of coffee, whose temperature is 90.0 °C and which contains 120.0 g of liquid. Assume the specific heat capacity of the coffee is the same as that of water. The heat of fusion of ice (the heat associated with ice melting) is 6.0kJ/mol. Find the temperature of the coffee after the ice melts. Use the equation given in the lab manual on page 86. Ignore the + (CC) (AT)...
